I recently learned about the pairwise test method.
It seems to be a technique to prevent the test cases from becoming huge.
There is Microsoft Pict as a famous CLI tool for generating pairwise test cases, but you have to compile it on your computer from source codes.
So, I created a online tool for creating pairwise test cases. It's powered by Microsoft Pict under the hood.
You can simply pass test elements to the left side and you'll get results. Ta-dah!
Happy Coding! :)
